`ni_tio_clock_period_ps()` used to return the clock period in
picoseconds, and had a `BUG()` call for invalid cases.  It was changed
to pass the clock period back via a pointer parameter and return an
error for the invalid cases.  Unfortunately the code to handle
user-specified clock sources with user-specified clock period is still
returning the clock period the old way, which can lead to the caller not
getting the clock period, or seeing an unexpected error.  Fix it by
passing the clock period via the pointer parameter and returning `0`.

Merge tag 'iio-fixes-for-4.9b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus

Second set of IIO fixes for the 4.9 cycle.

Interestingly scale related fixes for accelerometers at both ends of
the range.  Obviously more varied devices turning up than we've seen before!

* ad5933
  - fix an uninitialized value in a return case that is winding up GCC.
* hid sensors
  - missing pm function prevents hid rotations sensors from working on newer
  ISH hubs (works by luck on older ones)
  - increase of scale precision needed to fix a case where on a yoga 260
  the reported scale is 0 (presumably a high precision but very low g sensor).
* st_sensors
  - fix an issue seen with the hs3lis331dl where the range is much greater
  than previous devices (100's of g) and hence the per bit scale is greater
  than 1.

While testing, it was observed that on some platforms the scale value
from iio sysfs for gyroscope is always 0 (E.g. Yoga 260). This results
in the final angular velocity component values to be zeros.

This is caused by insufficient precision of scale value displayed in sysfs.
If the precision is changed to nano from current micro, then this is
sufficient to display the scale value on this platform.
Since this can be a problem for all other HID sensors, increase scale
precision of all HID sensors to nano from current micro.

Results on Yoga 260:

This fix makes newer ISH hubs work. Previous ones worked by lucky
coincidence.

Rotation sensor function does not work due to miss PM function.
Add common hid sensor iio pm function for rotation sensor.

Further clarification from Srinivas:

If CONFIG_PM is not defined, then this prevents this sensor to
function. So above commit caused this.

This sensor was supposed to be always on to trigger wake up in prior
external hubs. But with the new ISH hub this is not the case.

  The main problem with this change got fixed already, but we missed the

  is invoked, so the registration of the boot cpu which has the APIC bit

The recent changes, which forced the registration of the boot cpu on UP
systems, which do not have ACPI tables, have been fixed for systems w/o
local APIC, but left a wreckage for systems which have neither ACPI nor
mptables, but the CPU has an APIC, e.g. virtualbox.

The boot process crashes in prefill_possible_map() as it wants to register
the boot cpu, which needs to access the local apic, but the local APIC is
not yet mapped.

There is no reason why init_apic_mapping() can't be invoked before
prefill_possible_map(). So instead of playing another silly early mapping
game, as the ACPI/mptables code does, we just move init_apic_mapping()
before the call to prefill_possible_map().

In hindsight, I should have noticed that combination earlier.

Sorry for the churn (also in stable)!

Now that we have referece to section name string table in
apply_relocate_add(), use it to

 - print the name of section being relocated
 - print symbol with NULL name (since it refers to a section)

before

| rela->r_off | rela->addend | sym->st_value | ADDR | VALUE

|	40		0		7000a000  7000a0a0 7000a000 []

after

The loop was really needed in .debug_frame regime where wanted make it
as SH_ALLOC so that apply_relocate_add() would process it. That's not
needed for .eh_frame, so we check this in apply_relocate_add() which
gets called for each section.

Note that we need to save reference to "section name strings" section in
module_frob_arch_sections() since apply_relocate_add() doesn't get that

These are really ancient toggles and tools no longer require them to be
passed. This paves way for deprecating them in long run.
